What ever you do, do not purchase this item, it is not a worm and wheel. the worm has several straight groves in it, not a thread or spiral. It will not do anything as advertised. The worm will not turn the wheel as there is a fault in the manufacture. of the worm, ie it has groves not a spiral.

Buona manifattura. Come descritto dal venditore: corona da 40 denti e rapporto di riduzione 1:40 (40 giri di vite senza fine per 360° di rotazione del pignone). Sono compresi 2 grani brugola per il fissaggio sui rispettivi alberi.

Destiné à un entraînement horaire, l’engrenage a un bon aspect, à part un petit défaut sur la vis sans fin. A voir à l’usage ...
